BÖHLER L035 Engineering

BÖHLER L035 is a 35-cobalt-35-nickel-20-chromium-10-molybdenum wrought alloy (UNS R30035) used for the production of surgical implants. This alloy composition has been successfully used in human implants. Long-term clinical experience has shown an acceptable biological response.
The exceptional properties of BÖHLER L035 result from its chemical composition, high-quality melting technology, cold forming and heat treatment. It is a vacuum induction melted (VIM) and vacuum arc remelted (VAR) superalloy.

BÖHLER L035 is a nickel-cobalt based multiphase alloy system with a unique combination of properties e.g. extremely high strength, toughness, ductility and excellent corrosion resistance. The alloy can be strengthened and aged in the factory to achieve strength values of max. 260 to 300 ksi (1793-2086 MPa) and stress corrosion cracking (SCC) resistance even in hydrogen sulphide. The BÖHLER L035 alloy resists pitting and crevice corrosion caused by seawater, chloride solutions and other corrosive environments, e.g. mineral acids (nitric, hydrochloric, sulphuric acid).
